British Rail Class 37 Diesel Locomotive

Discover more about the English Electric Type 3, and its reputation for reliability on a whole different range of routes, all the way to the 1990s.

English Electric Type 3

The British Rail Class 37 Diesel Locomotive – also known as the English Electric Type 3 – was built at the Vulcan Foundry in Newton-le-Willows in a Co-Co configuration based on locomotive designs for export markets.

Trusted Workhorse

Built to undertake both freight and passenger work across all BR sectors, these engines proved highly reliable, and, after overhaul, many survived in service across the network into the 1990s.

Decline

As new ranges of diesel units became available for passenger services, the Class 37 went in to decline over time, but remains hugely popular with enthusiasts. A number have been preserved.
